HP EliteDesk 800 G3 Tower
Specification and Upgrade Options
The HP EliteDesk 800 G3 Tower is a pre-built business desktop computer first released in 2017. Although more than five years old, it is still a viable solution for home, office, and when properly upgraded – gaming. The motherboard is using the Q270 chipset and supports 7th gen Intel Core processor, 64GB of DIMM DDR4-2400 memory, and dedicated graphics card.
HP EliteDesk 800 G3 Tower is a Mini Tower form factor computer. The Mini Tower is the largest chassis in the business class desktops segment. If you are looking for a system with maximum upgradability, HP EliteDesk 800 G3 Tower is a good option. Models in this category usually have 4x PCIe slots, several drive bays and better cooling.
Can you upgrade HP EliteDesk 800 G3 Tower to play games?
Yes, you can upgrade HP EliteDesk 800 G3 Tower for gaming with better processors, graphics card, memory, and storage devices. However, like many other business pre-built PCs, this model may have proprietary elements like the power supply, the chassis or the power connector, which can make it difficult for users to install aftermarket PSUs to support better GPUs. You can also find that there is space constrains inside the chassis, making it difficult to accommodete larger GPU to boost the gaming performance.
Please explore the sections bellow to find ideas and suggestions on how to upgrade HP EliteDesk 800 G3 Tower.
Windows 11 compatibility
No, HP EliteDesk 800 G3 Tower does not meet the Windows 11 hardware requirements. According to Windows 11 specification, all models with Intel 7th Gen CPU or older are not officially supported. Processor with TPM 2.0 and a UEFI Secure boot BIOS is also required in order to upgrade from Windows 10 to Windows 11 through Windows Update.
However, anyone with PC that does not pass the upgrade test can download the official Windows 11 ISO, make a bootable flash drive, and install the OS manually.
You can upgrade HP EliteDesk 800 G3 Tower with a full size GPU. Models like NVIDIA GTX 1660 or GTX 1650 Super are good and safe upgrade option and will work with most Mini Tower form factor. However, keep in mind that the type of GPU you can install will depend on the available space in the chassis and the PSU power rating.
Before you begin shopping for a new GPU, it's important to consider the power supply unit (PSU) currently installed. This is because powerful GPUs require more power than the stock PSU can provide, which means that you may need to upgrade your PSU as well.
According to the manual, the maximum stock power supply available on HP EliteDesk 800 G3 Tower is 500W. However, to be absolutely sure, check the stock power supply power rating and use one of the GPUs from the table.

HP EliteDesk 800 G3 Tower has four RAM slots and supports dual channel memory configuration. This is sufficient for almost any use case and especially in situations where the workload calls for more RAM.
To cover the needs of your OS, games, and apps, HP EliteDesk 800 G3 Tower supports up to 64 GB of DIMM DDR4-2400 RAM. For office work, home use, and light gaming we recommend 8GB of RAM. For everything else, use 16GB or more.
Faster RAM speeds permit your processor to access the data stored inside the memory faster. This is important for the overall speed of your system. The motherboard of the HP EliteDesk 800 G3 Tower supports RAM speeds of up to 2400 MT/s.
HP EliteDesk 800 G3 Tower doesn't come with any on-board Wi-Fi support. In that case, you have two options to upgrade this model with Wi-Fi. You either use an external USB Wi-Fi adapter (wireless network dongle) or a PCIe-based wireless adapter.
The USB dongle is much more convenient and easy to install, but has less space for a decent antenna and can have thermal problems. On the other hand, the PCIe based adapter is much more powerful, more reliable, and has better antenna, but it is harder to install.
Wi-Fi and Bluetooth wireless adapter upgrades for HP EliteDesk 800 G3 Tower:
|WiFi 6E (Gig+) Kit||3000 Mbit/s||2.4GHz / 5GHz||NGFF M.2 A/E Key|
|Rekong AX210||3000 Mbit/s||2.4GHz / 5GHz||NGFF M.2 A/E Key|

Ports are important and often people don't think about them when buying a PC. For example, if you don't have enough USB ports, using external devices becomes problematic. Before you buy any system, considering your use case, check the number of external devices you are going to use and plan the number of the extension ports accordingly.
The HP EliteDesk 800 G3 Tower comes with ten USB ports in total. Having more USB ports is always better, but also pay attention to the version of those USB ports. Higher version ports support faster transfer speeds. Unfortunately, this model doesn't come with a USB 3.1 port. If you need a faster connection for your peripherals, like external Solid State Drive, you will need to choose another model.
The DisplayPort (DP) is the most widely used digital interface for transmitting digital video and audio between display devices and PCs. It is good to see that the HP EliteDesk 800 G3 Tower is featuring a DisplayPort 1.2. The post version is important if you target higher resolutions with high refresh rate. Although, ver. 1.2 is completely fine for most users, if possible, aim for the higher versions DisplayPort.
The HDMI port is another digital video port you can use to connect external display. It has very similar capabilities to the DisplayPort with few exceptions. However, the HP EliteDesk 800 G3 Tower doesn't have one. This is not a problem if there is on-board DisplayPort.
*Please keep in mind in order to use the video ports available through the motherboard, you need a CPU with integrated graphics card. If you have a dedicated GPU, use his ports instead.
SSD storage - M.2 sockets and SATA ports
The SATA port is one of the places where you can connect a stora gedevice. The HP EliteDesk 800 G3 Tower comes with five SATA port(s). Not enough SATA ports might limit your options for additional storage devices. Think about your use case and decide if the SATA ports provided by this model will be sufficient.
HP EliteDesk 800 G3 Tower has also one M.2 socket(s) that supports both PCIe NVMe (PCIe 3.0 x4) and SATA M.2 drives with speed of up to 4 GB/s. This configuration works very well for both gaming and work related tasks.
The M.2 PCIe SSD connector in combination with an NVMe drive allows for higher transfer rates, compared to the old SATA interface. In some situations, NVMe device connected to the M.2 PCIe socket can be more than 5 times faster.
